Development and adjustment in the field of a simulation model for calculating and evaluating the mineral requirement in beef cattle maintained on native grasslands
In order to develop a simulation model that reconciles the different biological-based mathematical algorithms used to calculate mineral requirements in beef cattle, bibliographic theoretical information has been compiled to lay the foundations for it. The model was developed in an Excel environment with the help of Excel macros. Two mineral samples were evaluated, simple mineral salt and protein salt for beef cattle. For validation were employed beef cattle with +/-290 kg body weight maintained on native pasture. Both, the mineral salt as the protein salt showed deficiencies to cover the mineral requirement of macro minerals, mainly phosphorus with a shortfall of 56 % in average. In the case of the trace minerals they were all covered sufficiently and expressed excesses principally in Fe and Mn, both for the mineral salt and for the protein salt. As for the simulations of daily weight gain, the software yielded results in both cases with lower daily weight gains than those obtained in practice, with a difference of 12%

El modelo fue desarrollado en entorno Excel con ayuda de macros Excel. En el mismo fueron evaluados dos formulaciones de suplementación mineral, sal mineral simple y sal proteinada, para animales bovinos de +-290 kg de peso vivo mantenidos sobre pastizal nativo, con el fin de validar el modelo. Tanto la sal mineral como la sal proteinada manifestaron deficiencias para cubrir el requerimiento de macrominerales, principalmente fósforo, con un faltante de 56% promedio, en el caso de los microminerales, todos ellos fueron cubiertos y manifestaron excesos en la oferta, principalmente Fe y Mn, tanto para la sal mineral como para la sal proteinada. En cuanto a las simulaciones de ganancia diaria de peso el software arrojó en ambos casos resultados con menores ganancias diarias de peso que las obtenidas en la práctica, con una diferencia del 12%.

O modelo foi desenvolvido em ambiente Excel com o auxílio de macros Excel. Nele, foram avaliadas duas formulações de suplementação mineral, sal mineral simples e sal proteico, para bovinos de +-290 kg de peso vivo mantidos em pastagem nativa, a fim de validar o modelo. Tanto o sal mineral quanto o sal proteico apresentaram deficiências para suprir a necessidade dos macrominerais, principalmente o fósforo, com déficit de 56% em média, no caso dos microminerais, todos foram atendidos e apresentaram excessos na oferta, principalmente Fe e Mn, tanto para o sal mineral quanto para o sal proteico. Com relação às simulações de ganho de peso diário, o software apresentou resultados em ambos os casos com ganhos de peso diários inferiores aos obtidos na prática, com uma diferença de 12%.
